Help on list object:

class list(object)

| list() -> new empty list

| list(iterable) -> new list initialized from iterable's items

| Methods defined here:

| __add__(...)

| x.__add__(y) <==> x+y

| x.__contains__(y) <==> y in x

| __delitem__(...)

| x.__delitem__(y) <==> del x[y]

| __delslice__(...)

| x.__delslice__(i, j) <==> del x[i:j]

| Use of negative indices is not supported.

| __eq__(...)

| x.__eq__(y) <==> x==y

| __ge__(...)

| x.__ge__(y) <==> x>=y

| __getattribute__(...)

| x.__getattribute__('name') <==> x.name

| __iadd__(...)

| x.__iadd__(y) <==> x+=y

| __imul__(...)

| x.__imul__(y) <==> x*=y

| __setitem__(...)

| x.__setitem__(i, y) <==> x[i]=y

| __setslice__(...)

| x.__setslice__(i, j, y) <==> x[i:j]=y

| Use of negative indices is not supported.

| __sizeof__(...)

| L.__sizeof__() -- size of L in memory, in bytes

| append(...)

| L.append(object) -- append object to end

| count(...)

| L.count(value) -> integer -- return number of occurrences of value

| extend(...)

| L.extend(iterable) -- extend list by appending elements from the iterable

| index(...)

| L.index(value, [start, [stop]]) -> integer -- return first index of value.

| Raises ValueError if the value is not present.

| insert(...)

| L.insert(index, object) -- insert object before index

| pop(...)

| L.pop([index]) -> item -- remove and return item at index (default last).

| Raises IndexError if list is empty or index is out of range.

| remove(...)

| L.remove(value) -- remove first occurrence of value.

| Raises ValueError if the value is not present.

| reverse(...)

| L.reverse() -- reverse *IN PLACE*

| sort(...)

| L.sort(cmp=None, key=None, reverse=False) -- stable sort *IN PLACE*;

| cmp(x, y) -> -1, 0, 1

| ----------------------------------------------------------------------

| Data and other attributes defined here:

| __hash__ = None

| __new__ = <built-in method __new__ of type object>

| T.__new__(S, ...) -> a new object with type S, a subtype of T
